| 摘 要： | 以三级生化处理后的炼油污水为研究对象,考察了催化氧化过程的氧化作用和混凝作用,结果表明,催化氧化法去除有机物主要通过将大分子有机物氧化分解为小分子有机物,从而提高污水的可生化性;催化氧化对有机物氧化具有选择性,对苯甲酸和苯胺等芳香类化合物去除效果好,去除率分别达到92.2%和84.8%;对草酸和乙酸等小分子有机酸去除效...

| Abstract: | The tertiary biochemical treated refining wastewater was further treated by catalytic oxidation. The results show that the organic macromolecules in the refining wastewater are degraded into smaller ones by catalytic oxidation, resulting in the improvement of the biodegradability. It selectively oxidizes benzyl acid and aniline effectively with the removal rate of 92.2% and 84.8%, respectively; however, it is less effective to the acetic acid and oxalic acid with the removal rate of 13.5% and 10.6%, respectively. |
